trained by the manufacturer.
Before putting dampers into service after installation 
(and in subsequent periodic inspections) visual inspection 
and functional test must be conducted. After the visual 
inspection and functional test a record must be made into 
operational diary (page 6).
2 Operating and Maintenance
2.1 The damper operation
After installation, the damper must be set up into the 
operating position - closed. By connecting a power source 
to activate the actuator the blade shall move. Respective 
switching power supply achieves entry into the operating 
position - closed. 
2.2 Maintenance
Systemair smoke dampers are maintenance free.
3 Check of the functionality
Switching the supply phase according to Figure 3 - 7 damper 
switch to the „open“:
•  The blade must come to the fully open position and must 
remain there detented.
•  After reaching the end position of the blade the appropriate 
signaling circuit must switch on.
Switching the supply phase according to Figure 3 - 7 switch 
damper to the „closed“:
•  The blade must come up to the fully closed position 
and remain there detented.
•  After reaching the end position of the blade the appropriate 
signaling circuit must switch on.
Now the damper is in standby mode, so it must rest for normal 
operation.
4 Inspection of the damper
Each damper should be inspected after installation and every 
12 months using following steps:
1.  Identication of damper
2.  Date of inspection
3.  Check of the electrical connection of the activation 
mechanism
4.  Check of the the electrical connection of the end switches
5.  Check of the damper for cleanliness and eventually 
treatment (where necessary)
6.  Removing of the cover of the inspection lid.
7.  Check of the inspection lid, cover tightness and eventually 
correction and record (where applicable)
8.  Check of the blade and sealings, and eventually correction 
and record (where applicable)
9.  Check of the safety damper closure - details see Chap. 3
10. Check of the damper functionality (details see Chap. 3) 
opening and closing by the control system, tracking 
the physical behavior of the dampers and signalization 
of the end positions, and eventually correction and record 
(where applicable)
11. Closing of the cover of the inspection lid.
12. Set up into the operating position - see Chap. 2.1
13. Record into operational diary (page 6) with name 
and signature of the checker.
5 Warranty conditions:
1.  IMOS-Systemair a.s. provides warranty for all its DKI smoke 
dampers. The warranty period is 24 months, starting on 
the date of product shipment, by an exceptional agreement 
this period can be up to 30 months, starting on the date of 
shipment.
2.  The product is tested in the production factory before 
the shipment. The producer guarantees that the product 
features shall be in accordance with the related technical 
standards during the whole warranty period, assuming 
that the customer uses it in a way that complies with the 
Operation manual. If, in spite of this, any unpredictable 
production defects occur, the producer shall secure their 
removal without charge.
3.  The customer may apply for the warranty service only in 
written form including serial number of the claimed damper.
4.  The warranty does not apply to defects caused by 
unprofessional handling, incorrect mounting, mechanical 
damage or not following the instructions stated in the 
Operation manual.
5.  The warranty period shall be prolonged for the same period 
of time which has elapsed between the date when the 
customer lodged the claim for warranty service and the date 
when the repair was carried out.
6.  The repair shall be carried out at the customer’s premises and 
the producer shall bear all the costs which are necessarily 
needed for the repair.
7.  In case no defects applicable for warranty are identied, the 
costs associated with the arrival of the service technician will 
be handled by the customer who led the warranty repair 
claim.
8.  Before you can install the smoke damper, it‘s functionality 
must be tested according to the chapter 3 Check of the 
functionality.
DO NOT INSTALL NONFUNCTIONAL SMOKE DAMPERS!
Changes of smoke damper functionality, caused by transport 
or installation, aren´t reclaimable after the installation 
(deformations, damages, mechanical damage of the sealing 
material, foreign objects which can constrain the blade, 
wrong handling of the activating mechanism etc.)
9.  Before you can connect the smoke damper into the 
ductwork, smoke damper‘s functionality must be checked 
again (according to chapter 3 Check of the functionality).
IT IS NOT POSSIBLE TO CLAIM FAULTY FUNCTIONALITY CAUSED 
BY PRODUCTION, TRANSPORTATION OR INSTALLATION AFTER 
CONNECTING THE DUCTS TO THE SMOKE DAMPER!
The dampers are transported in covered means of transport,  
on pallets or in boxes. When handling during transportation  
and storage, the dampers must be protected against damage 
and weather conditions and the damper blades must be in  
the closed position. These products must be stored in a closed 
and dry area where the temperature is kept within the range  
of -20 °C to +50 °C.
The damper is part of the SHEVS. Therefore the system must 
be checked as specied in its operational and maintenance 
requirements.
